Since you've got a DECwindows connection into VMS, you should be
able to create a DECterm with no process on it to use for the
debugger session.  I.e. something like:

$ @detached-debug lnm$process

Where detached-debug.com is given below.  (It's designed for
running a debugger on a detached image, but can be used in your
application too.)

Cheers,

Aaron
